CONE FRICTION-COUPLING.

Specification of Letters Patent.

Patented Feb. 4, 1908.

Application filed October 2. 1905. Serial No. 281.088.

To all whom it may concern: I

Be it 'known that I, HUGO BAUMGAR NEE- MK'JA, citizen of Switzerland, residing at Basel, Switzerland, have invented new and useful Improvements in Cone Friction-Couplings, of which the following is a specification.

This invention relates to a cone friction coupling which has a double cone slidable upon the driving member and a pulley havdriven member and a cone ring by means of cone ring and under the influence of springs. The slidable cone ring-and the said double the said pulley cone ring and thus brought in frictional contact with each other. The. said slidable ring carries other bolts passing through corresponding holes in the said pulley cone ring which serve as disengagmg bolts and are actuated by suitable members Springs are also employed which tend to i move the said double cone out of frictional contact with the said pulley cone ring when uncoupling. I attain this by the mechanism illustrated in the accompanying two sheets! Figure 1 is a side view and Fig. 2 a longitudinal section on line :10, y, z of Fig. 1, of one form in which my invention may be carried out. Fig. 3 is a detached longitudinal section on an enlarged scale.

Similar letters refer to similar parts throughout the several views.

A is the double cone slidable on the shaft I.

B is the pulley to be coupled keyed upon the shaft II, and C the cone ring pressed againstthe double cone A and by bolts a slidably connected with the pulley B. Upon the bolts (1 are springs b capable of being tensioned by means of the washer c and nut d. 1

e are disengaging bolts screwed into the slidable cone ring G and held fast therein by lock nuts e. In .eyes on the ulley cone ring B studs f are employed W ch receive the levers g, each having a-cam projection g on its boss.

h is a disengaging sleeve having screwed therein a stud h engaging in-the slots g of the levers g. are secured two screws i passing throughcorresponding holes in a ring 7c secured upon the shaft I. 'Thesescrews carry each a sprin l and a washer and nut-Z- for tensioning t e springs I so that when the coupling is out of frictional contact, the double cone is drawn back againstthe ring 7c.

The cone friction coupling described operates as follows: Normally the double cone A is held in frictional contact with the pulley cone ring B throu h the medium of the cone ring C, bolts a an springs b, the two shafts I & II being then coupled up. When it is desired to uncouple the said shafts the sleeve h is moved outwards'which causes the cams g on the levers g to depress the bolts 6 and In the boss of the double cone N thereby push the cone ring 0 out of contact I been pushed clear of the cone A the shaftsI & II- are completely uncoupled.

l/Vhat I claim as my invention and desire to secure by Letters Patent, is,

Ina double cone friction coupling, a driving shaft and a driven shaft in line with each other, a single cone secured to the said driven shaft and having holes, a sin le cone ring slidable on the said cone, a dou le cone slidably secured to the said driving shaft to rotate the-said single cone and cone ring, bolts secured to the said cone" ring passing through the said holes and springs thereon for holding the said cone. ring in contact with one side of the said double cone and the 'other side of the latter in contact with the said single cone,means for moving the said cone ring out of contact with the said double cone and sprin s for moving .the latter out of contact with t e said single cone, all combined substantially as and forthe pur pose'set forth. 1

In testimony whereof I. have signed my name to this specification'in the presence of two subscribing witnesses. v
